  • Patent number: 12628661
    Abstract: A chip package having die pads with protective layers is provided. At least one protective layer is covering and arranged at a peripheral zone of at least one die pad for minimizing area of the die pad exposed outside as well as shielding and protecting the peripheral zone of the die pad. A weld zone of the die pad is not covered by the protective layer so that the weld zone of the die pad is exposed. In a crossed-over state, one of bonding wires crossing one of the die pads with a corresponding connection pad of a carrier plate will not get across a second upper space defined by the weld zone of the rest of the die pads. Thereby the one of the bonding wires can be more isolated by the protective layers on the peripheral zones of the rest of the die pads.

  • Patent number: 12482771
    Abstract: A chip package with higher bearing capacity in wire bonding is provided. The chip package includes at least one conductive circuit which is a structure with a thickness ranging from 4.5 ?m to 20 ?m. Thereby a structural strength of the conductive circuit is improved and able to stand a positive pressure generated in wire bonding or formation of a first bonding point. Thus at least one internal circuit of a chip will not be damaged by the positive pressure and allowed to pass through an area under the first bonding point or arrange under the first bonding point. A problem of increased cost at manufacturing end caused by the internal circuit redesign of the chip can be solved effectively. This is beneficial to cost reduction at manufacturing end.

  • Patent number: 8815645
    Abstract: A multi-chip stacking method to reduce voids between stacked chips is revealed. A first chip is disposed on a substrate, and a plurality of first bonding wires are formed by wire bonding to electrically connect the first chip and the substrate. A second chip is disposed on an active surface of the first chip where a FOW (film over wire) adhesive is formed on a back surface of the second chip. The FOW adhesive partially encapsulates the first bonding wires and adheres to the active surface of the first chip. Then, the substrate is placed in a pressure oven to provide a positive pressure greater than one atm during thermally curing the FOW adhesive with exerted pressures. Accordingly, voids can be reduced inside the FOW adhesive during the multi-chip stacked processes where issues of poor adhesion and popcorn between chips can be avoided.

  • Patent number: 8361841
    Abstract: Disclosed is a mold array process (MAP) method to encapsulate cut edges of substrate units. A substrate strip includes a plurality of substrate units arranged in a matrix. Scribe lines are defined between adjacent substrate units and at the peripheries of the matrix where pre-cut grooves are formed along the scribe lines with a width greater than the width of the scribe lines. An encapsulant is formed on the matrix of the substrate strip to continuously encapsulate the substrate units and the scribe lines to enable the encapsulant to fill into the pre-cut grooves to further encapsulate the cut edges of the substrate units. The cut edges of the substrate units are still encapsulated by the encapsulant even after singulation processes where substrate units are singulated into individual semiconductor packages to prevent the exposure of the plated traces of the substrate units to enhance the moisture resistance capability of the semiconductor packages.
